To all/w hom t may concern, l Beit-known that'I, JOHN W. WATKlNsoN,

a citizen of the United States, residing Charleroi, in the county of Washington and State of Pennsylvania, have invented certain new 'and-useful Improvements in-YBuildin'g Blocks; and I do hereby declare the follow? y ing to be -a full, clear, and exact description Y other.

The invention has for a still further object the provision of an improved form of building` block of the character stated in which the blocks will be provided with interlocking grooves and ribs or tongues and the corner blocks also being provided wita transverse partition which will limit sliding movement of the side wall blocks thereon so as to be sure of proper arrangement of the blocks with respect to one another.

nearer one end. The opposite end carries a With the foregoing and other objects in view as will appear as the description proceeds, the invention consists in the' novel construction, combination and arrangement of cooperating elements as hereinafter more specifically set forth, pointed out kin the appended claims, and shown inthe accompanydepending centraltongue 3 on its lower face while a corresponding recess or groove .4. is formed centrally in the upper face of the last mentioned end V.which end may be designated by the numeral 5.

In connection with the corner block-'just described, lpropose to employ side wall blocks 6` which are alsoi'hollow and have open opposite ends, each side wall block 6 being provided upon its lower face with a longitudinal central rib 7 while a correspondl loro s ingly depressed portion or groove 8 is formed in its upper vorcentral face.y l i `The blocks 1 and 6 may be formed of plastic material or anyv'othervsuitable'material and may be of any convenient or appropriate sizes. It is also to be understood form and corresponds in size to thecorner block l.

BY the Proper use 0f the twoblocks above i' v v i that the block 6 is'of elongated rectangularry constructed and the blocks of each layer and of each wall securely locked together and held against slipping or other independent movement of one another.

In building the structure from the blocks forming the subject matter of this invention, it is advisable to first provide a base of con? v crete'or the like foreach wall forming a part of the proposed structure. The blocks to be ond layer is then formed byf placing the blocks for the second layer of each ywall in overlapping` :relation with respect to the yblocks of the irst layer or lowermost layer the wall; In the case of the second layer of blocks,'the corner block isv employed for `theother wall and the smooth end placed transversely across the smooth or outer end of the corner block in the remaining wall of the first layer. The transverse partition v2 not only serves to strengthen the corner v bloclrl but also serves as a stop to be engaged bythe end of the rib 7 on the side block extendedfover theinner end of the corner block and as will also be Areadily understood by rreferring to the drawings; ByY

reversing the corner blocks for each layer of the Vwalls at right angles to one another, as

justpdes'cribed, theside wall blocks of each layer will be.. offset` or 'overlapped with respect tothe side wall blocks of the layers im- Ymediately above and below the same, thereby properly breaking. thev joint between the blocks of the various layers of the wall structure. Y

j-It is to be understood that while the preferred embodiment of the invention has been shown and described, minor changes inthe details of construction and arrangement of parts `may' be resorted to within the scope of what is claimed without departing from the l spiritv ofthe invention.
